A man stabbed two others at flats in Wakefield where his mother lived fuelled by a cocktail of drink and drugs, a court heard.
Luke Grainger later admitted having drunk 20 cans of lager and two litres of vodka and taken drugs that day before going to the address in Pinderfields Road.
Jailing him at Leeds Crown Court yesterday, the Recorder of Leeds, Judge Peter Collier QC, said Grainger believed the two men had been taking the “micky” out of his mother Samantha Hutchinson, although she told him that was not the case.
He armed himself with a vegetable knife and went upstairs to a flat where, having been let in by Carl Scott, 36, who knew him, he suddenly attacked him.
He stabbed him six times in his chest, back and abdomen “fortunately causing no damage to underlying organs”.
Grainger then went downstairs where Mark Millard, 33, had just entered the foyer after returning from a night out and attacked him.
Mr Millard thought he was being punched but he was actually being stabbed.
He was cut on his face and suffered five wounds to his shoulder and back but was fortunate to also have made a good recovery. Grainger fled but rang police the next day and told them where he could be found, said John Bull, prosecuting. His recollection of events was sketchy because of the alcohol he had drunk.
The court heard that in October 2011 Grainger had twice been found carrying a large knife for which he was sentenced to nine months detention in a young offender institution.
Sam Andrews, for Grainger, said he was over-protective of his mother who had mental health problems, but was remorseful.
Grainger, 21, of Hoyland Road, Wakefield, was jailed for six years with his licence extended for a further four years after admitting two charges of wounding with intent on October 28, last year.
Judge Collier said he considered Grainger posed a risk to the public “unless and until you change your patterns of behaviour and find ways of dealing with your inner demons”.
